Forum Post: UCD9090 watchdog

$

I'm trying to disable the watchdog function dynamically.

The device is programmed with the WD enabled. When we send an I2C command to disable it (either from the Fusion GUI or our application), the command takes effect only after the next cycle: ie a reset is generated by the WD (as if no command was sent), but after that last reset no further resets are generated (as if now the command took effect).

What is the procedure to disable the WD immediately? (ie preventing any further reset pulses)
